Accessibility features

Voice feedback helps people with vision problems to use their phone. When enabled, a voice prompt helps you navigate the phone screen and use or configure phone features.

The voice also reads out incoming caller IDs, touchable area information, screen summary, virtual keyboard keys,hard keys, and softkey information.

To have a better visual experience, you can customize the font size when the phone is taken out-of-box. The customization of the font size does not change few of the texts, such as the texts on the phone header, some descriptional small texts, large text on the phone Home screen, texts in the softkey bar. If key expansion module is connected to a phone, font size of the text in KEM also changes during this customization.

For more information on configuring voice feedback on the phones registered to Cisco BroadWorks or Webex Calling, see Configure voice feedback.

For more information on configuring from phone, see Voice feedback (accessibility).

For information on font change, see Customize font size on your phone.

Cisco Headset USB-C Adapter support

The phones now support Cisco Headset USB-C Adapter for the connection with Cisco wireless headsets.

For more information, see Cisco Headset USB Adapter.

MRA onboarding with domain service

You can use the service domain onboarding with Mobile and Remote Access (MRA) when deploying your phones for remote users. When users choose and enter a valid service domain, they will be prompted to enter their user credentials for the MRA authentication.

For more information about the feature, go to the following links:

User credentials persistent for Expressway sign-in

User login credentials can be stored on the phone after the user signs into the Expressway server for Mobile and Remote Access (MRA). If enabled, the users don't need to enter the credentials again even though the phone restarts.

For more information about the feature, see Configure user credentials persistent for Expressway sign-in.

Forced Authorization Code (FAC) and Client Matter Code (CMC)

You can configure the phone to require the users to enter FAC or CMC, or both before they dial out a specific phone number. By using FAC and CMC, you can effectively manage call access and accounting. FAC regulates the types of calls that certain users can place, CMC assists with call accounting and billing for clients.

For more information about the feature, go to the following links:

Switch for UDS directory service on Unified CM

The User Data Service (UDS) is used as the default directory service for phone on Unified CM. You can disable the service either for all phones or for an individual phone if you don't use it. When disabled, users on the phone can't view the personal or corporate contacts provided by UDS.

For more details, see Configure directory services for phones on Unified CM.

Assured Services SIP (AS-SIP)

Assured Services SIP(AS-SIP) is a collection of features and protocols that offer a highly secure call flow for Cisco IP Phones and third-party phones. AS-SIP is often used with Multilevel Precedence and Preemption (MLPP) to prioritize calls during an emergency.

For more information, see Assured Services SIP.

Certificate Authority Proxy Function (CAPF) with Elliptical Curve (EC) key support

In the previous release, only the RSA key is supported in CAPF. Now, the EC key is also supported. To use the EC key, make sure that the parameter "Endpoint Advanced Encryption Algorithms Support" (from System > Enterprise Parameter) is enabled.

For more information about this feature, see the following documents:

Mute status synchronization

The mute status is synchronized automatically between the phone and the Cisco Meeting Server (CMS) server.

When the user toggles the microphone on or off on the phone, the mute status is synchronized to the CMS server automatically, and vice versa.

For incoming calls, it's required for the user to choose to mute or unmute the microphone.

This feature supports USB headsets and the Cisco Headset 720/730 (with Bluetooth-paired).

For more information about how to configure CMS on Cisco Unified Communications Manager, see the following document:

Installation requirements

Before you install the firmware release, you must ensure that your Cisco Unified Communications Manager is running the latest device package. After you install a device package on the Cisco Unified Communications Manager servers in the cluster, you need to reboot all the servers.

If your Cisco Unified Communications Manager doesn't have the required device package to support this firmware release, the firmware may not work correctly.

Before using the phone firmware release, you must install the latest Cisco Unified Communications Manager on all Cisco Unified CM servers in the cluster.

By default, your phones are set up for the English (United States) locale. To use the phones in other locales, you must install the locale-specific version of the Unified Communications Manager Endpoints Locale Installer on every Cisco Unified Communications Manager server in the cluster. The Locale Installer installs the latest translated text for the phone user interface and country-specific phone tones on your system so that they are available for the Phones.

To access the Locale Installer required for a release, access the Software Download page, navigate to your phone model, and select the Unified Communications Manager Endpoints Locale Installer link.

For more information, see the documentation for your particular Cisco Unified Communications Manager release.

The latest Locale Installer may not be immediately available; continue to check the website for updates.

Anything that degrades network performance can affect phone audio and video quality, and in some cases, can cause a call to drop. Sources of network degradation can include, but are not limited to, the following activities:

  • Administrative tasks, such as an internal port scan or security scan.

  • Attacks that occur on your network, such as a Denial of Service attack.

This product is not a medical device and uses an unlicensed frequency band that is susceptible to interference from other devices or equipment.

When the Cisco Unified Communications Manager Transfer On-Hook Enabled field is enabled, users might report a problem with direct call transfer in SIP phones. If the user transfers the call and immediately goes on hook before they hear the ring signal, the call may drop instead of being transferred.

The user needs to hear the ring signal so that they can be sure that the call is being routed.

Use the following sections to obtain related information.
